To all whom easy concern:

Be it known that I, WILLIAM Barnes, a subject of the King ofEngland,'residing at 22'Victoria road, Crosby, near Liverpool, in thecountyof Lancaster, England, have invented new and useful Improvementsin or Connected with Motor-Cycles, of which the following is aspecification 1 V This invention has reference primarily to the pro,-pelling of cycles by auxiliary motor mechanism, so, 10

that a cycle, say an existing cycle, or the ordinary type of cycle,canhave attached to it such a mechanism, and used as a mdtor-cycle, oralternatively, if and when desired, as an ordinary foot propelled cycle,by simply detaching the mechanism, which is so constructed and arranged,as hereafter described, as to be capable of being easily and quicklyattached, and detached. I The drawings hereto annexed illustrate anauxiliary motor mechanism according to my invention as apit comprises anupright part consisting of a plurality of vertical members 1 (two in thecase shown) on each side, and an upper horizontal member 2, to which themembers 1 are attached. .The'bottom connections of the members 1 at theone side consists of a tube 3, and at the other, of the upper part ofthe motor 4.

The road wheels 5 are mounted on axles 6, and are drivenby sprocketwheels '7 connected with them, as hereinafter described." i

In the. upper tube 2 is a shaft 8, driven by the motor 4.through asprocket chain 9, and sprocket wheel 10, connected with a differentialgear 11 of any suitable kind on said shaft; and from this shaft 8 theroad wheel sprocket wheels 7 are'driven by sprocket wheels 12 on saidshaft 8, and chains 13. Thus, motion from the motor is transmitted tothe road wheels 5.

I The attachment of the motor frame to the cycle frame is by a clampingdevice at the top, and through a con-' nection with the axle of thecycle road wheel below. The top clamp consists of a boss 14 fitting overthe tube 2, and having a bolt 15,. which passes through a plate l6, theinner face of which is grooved to fit the cycle back fork. A'filling.block 17 is placed between the tubesl ii of the back fork and the tube2. The two upwardly projecting jaws 19 on the lower inner ends of themotor frame tubes 3, grasp an extension 20 of the axle of the rear wheel21 of thebicycl'e, These parts 19, 20, may be bound, by nuts or anysuitable fastening device. By adjusting and fixing the motor frame onthe bicy- Specification of Letters Patent. I Application filed May22,1906. Serial No. 318,246.

cle frame at the required height, it can be so arranged that any desiredproportion of pressure-say one .thirdof/the rear road wheel 21 of thecycle may come upon the road; or, this road wheel may be kept off theroad entirely. But if it be arranged to bear on the road, by propellingthe cycle by the ordinary pedals with-the feet, the engine 4 can bestarted after the rider gets 'onthe machine; while, if the road wheel 21be off the road, the engine has to be started before the rider gets on.

On the motor frame in Figs. 1. to 3, the oil tank 22 is placed on theside of the bridge frame opposite to that on which the motor is placed.

Referring now to the modification shown in Figs. 4 and 5, the topattachment of the frame is by diagonal connecting bars 23 which arefastened bybolt clamps 24 to the tube 2, and to the bolt 25 at the otherend which secures the back forks 18 of the bicycle'at the top to theordinary seat pillar socket. Additional connecting tubes 26 extendbetween the tubes 23 and the inner vertical tubes 1, such tubes beingconnect-ed to hinges supported by clamp fastenings 27, 28, at theirends. B ythe fastenings 24, and 27 28, being bolted to clampingfastenings, they can be adjusted to any position to suit different sizesof bicycles. The fastening between the frame tube a and the projectingpart 20 of the axle of the wheel 21, consists of socket pieces or anysuitable known kind of gearing. Also, in lieu of utilizing thedifferential gear 11, the sprocket Wheels j may be mounted asfree-wheels to revolve freely one way, but grip the other.

What is claimed is': p ,1. In an auxiliary motor mechanism constructedand adapted to be readily attached to, and detached from a man-powerdriven 'cycle,.for converting same at will to a.

motor cycle, a frame consisting of two side parts 1, and an uppertransverse part 2 connecting the said two side frames together; a shaft8 extending through the said tube 2, with gear wheels on each side, andby sprocket or other gear wheels connected with the two road wheels 5,one on each side of and connected to the lower part of said'trame, and amotor 4 111 one of the side portions of the frame, geared with the saidshaft 8 by sprocket wheels'and chains substantially as set forth. 4 2.An auxiliary motormechanism of the kind herein described, constructedand adapted to be readily attached to, and detached from, a manpowerdriven cycle, for converting same at will to a motor cycle, a frameconsisting of two side parts 1 and an upper transverse part 2 connectingthe said two side frames together aJShuft 8 extending through the saidtube 2, with gear -wheels on each side, and by sprocket or othergeariwheels connected with the two road wheels 5, one on each side ofand connected to the lower part ofsaid frame, and a motor 4 in one ofthe side portions of the frame, geared with the said shaft 8 by sprocketwheels andchains, an attaching and detach- .ing means at the upper partofsaid frame 1, 2, for connecting it to the upper renrpo'rtl onof thecycle and attaching devices on the lower part of the'frame parts 1adapted to engage with projecting pa'rts 2011i: the axle of the wheel 21of the cycle;- substantially as set forth.
